実験手順

A mixture of 370 mg (0.88 mmoles) of (1,1-dimethylethyl) 3-[(6-chloro-5-methyl-4-pyrimidinyl)amino]-N-[(phenylmethoxy)carbonyl]alaninate and 1.0 g (1.79 mmoles) of 1,2,3,4-tetrahydro-7-(4-piperidinyl)-1,8-naphthyridine, tris (trifluoroacetate) (prepared according to Patents EP 1065207 or WO 0078317) in 1 ml of diisopropylethylamine is heated at 120° C. for 2 hours. Then 10 ml of xylene is added and the medium is taken to reflux for 4 hours. The reaction medium is taken up in a mixture of water, ethyl acetate and a saturated solution of sodium bicarbonate. The organic phase is decanted and the aqueous phase is reextracted with ethyl acetate. The combined organic phases are dried over magnesium sulphate and evaporated to dryness under vacuum and the residue is chromatographed on silicagel with a gradient of 100% ethyl acetate to a mixture of ethyl acetate-methanol-triethylamine-dichloromethane 50-10-10-50.32 mg (Yield=6%) of expected product is obtained and 200 mg (54%) of chlorinated starting product is recovered.
